Major code rewrite / cleanup. closes #56 #60

- MBProgressHUD now requires LLVM 3+

- instance variables moved to the class implementation or removed (using synthesized instance vars)
- using KVO instead of custom accessors
- completely rewritten layout and UI buildup code
- more concise arc conditionals
- added MBProgressHUDModeText (+ example)
- various documentation fixes
- migrated to @autoreleasepool
- general source code cleanup and restructuring
- removed deprecated delegate callback
- version bump to 5.0

 3. Open your project in Xcode, than drag and drop `MBProgressHUD.h` and `MBProgressHUD.m` to your classes group (in the Groups & Files view). 
 4. Don't select Copy items and select a suitable Reference type (relative to project should work fine most of the time). 
 
+You can also add MBProgressHUD as a static library to your workspace. See [this article](http://blog.carbonfive.com/2011/04/04/using-open-source-static-libraries-in-xcode-4/#using_a_static_library) for details.
